DESCRIPTION

The SJA1117B-XXX is a series of low dropout

three-terminal regulators with a dropout of 1.15V(typ.)

at 1A output current.

The SJA1117B-XXX series providescurrent limiting and thermal

shutdown. Its circuit includes a trimmed bandgap. reference to

assure output voltage accuracy to be within 1.5%. Current limit

is trimmed to ensure specified. output current and controlled short-circuit

current. On-chip thermal shutdown provides protection against any

combination of overload and ambient temperature that would create

excessive junction temperature. The SJA1117B-XXX has an adjustable

version, that can provide the output voltage from 1.25V to 5V with

only 2 external resistors.
